Centrafuse/Destinator Route Color and Navigation Zoom Level

Is it possible to adjust the color of the route? It is quite hard to see on my screen and at a quick glance looks like side roads. I'd like to make the entire route stand out rather than just have blueish boarders. Also, is it possible to change the zoom level to increase the size of the roads. The roads on my screen are very narrow making it hard to follow the route or even see which road the route actually follows. Any help is much appreciated.
